Overview
About the WANH3-N 2001 Ammonia Nitrogen Analyzer.
The WANH3-N 2001 ammonia nitrogen analyser is an online monitoring instrument for water and wastewater. It measures ammonia nitrogen by salicylic acid spectrophotometry, working to the technical requirements of HJ/T 536-2009, and combines constant optical fibre measurement with integrated digestion and colorimetric technology. Photoelectric sampling keeps injection error low, while automatic chromaticity and turbidity compensation accounts for real sample conditions. A specially designed flow path prevents blocking, and bubble agitation mixes sample and reagents thoroughly. The analyser runs hourly or interval measurements, and its self-diagnosis, alarms and quality-control functions support reliable long-term online operation.
